The 18-year-old Watford defender, who recently had a spell on loan at Brentford, has moved to The Bees on an initial one month loan deal.
"At the moment we have several defenders whose injuries need careful managing and monitoring and I was delighted to secure the services of Jordan," Barnet boss Paul Fairclough told his club's official website.
"It is a great bonus that he can play in both full-back positions and he will be involved in our game against Chester this Saturday."
